As a manager, it’s very easy to quickly lose your technical edge. Most of your day will get filled with meetings, planning sessions, strategy sessions, tactical status updates, 1 on 1’s, etc. On top of a day filled with meetings you will need to figure out how to execute various initiatives, and spend nights catching up on email.
Given the above time and mindshare constraints, how can anyone expect you to have time to keep up with technical skills?
The simple answer is, “it doesn’t matter”, you need to figure out a way to do it regardless!
